APPARATUS FOR MANUFACTURING. TIRES ORINTERLINERS.

To all whom it mayconccrn:

Be it known that I. WILLIAM F. RAY, a

cil men of the United States, residing at Chicago, in'the'county of Cook and State of Illinois, have invented a new and useful lmprovenient in Apparatus for Manufacturing Tires or Intcrliners, of which the following a specification.

This invention relates particularly to apparatus for use in the manufacture of a puncture-proof inner casing or interliner, or puncture-proof tire; and the invention iswell adapted to use in the manufacture of a tire, or interliner, of the character described in my Patent No. 1,251,576, granted January 1st, 1918.

The primary object is to provide a simple and cheap device or apparatus which is adapted for use in the economical manufacture of a tire, or interliner, of the character mentioned.

The invention is illustrated, in the preferred embodiment in the accompanying drawings, in which Figure 1 represents an elevational view of the improved apparatus, the-view showing certain parts brokenly; Fig. 2, a broken plan View of a tire, or interlincr, for use in the manufacture of which the improved apparatus is particularly useful; Fig. 3, a secdevice and the templct which is employed for spacing the inner series of steel strips which enter into the construction of the inte'rliner, or tire,the section being taken as indicated at line 3 of Fig, '4; Fig. 4, a

broken plan view illustrating the'carcass in process of construction; Fig. 5. a section similar to Fig. 3,but showing the tcmplet em ployed for spacing the steel strips of t.h e

outer series; Fig. 6, a broken plan VIOW simllar to Fig. 4, but illustrating the spacing of the steel strips of the outer series; Fig. 7, a

A ,upon which is mounted a rotatable spider A; B, an annulay core or mandrel mounted on the spider A O, a pair of templet-supports carried by the mandrel; and C and G a pair of annular templets, one of which used inplacing the steel strips of the inner series and the other of which is used 7 in placing the steel strips of the outer series.

The frame, or mounting, A, may be of any suitable construction. The form illustrated is Well adapted to support the man.

drel and permit it to be turned as may be necessary in the operation of building up the tire structure.

The mandrel B may be constructed in any desired manner. In the illustration given,

the mandrel comprises a hollow metal an nulus.

The templet-suppor'ts-C, of which there are two, are detachably mounted .in the inner periphery of the annular mandrel in the manner illustrated in Fig. 8. Each support C comprises a post 1 equipped with cross-arms 1 and 1*, each of whic IS adapt ed to serve as one of the supports for an annular templet. The post 1 is of square socket 2 which is firmly secured in the mom drel, the socket being open at its inner end to permit insertion or withdrawal of the post 1. The post 1 is held securely in place by frictional contact with the socket. The member C is'provided witha knob, or han dle, 1, to facilitate the" insertion or with- ,drawal of the post.

cross-section and fits snugly in a radial The templet 0 comprises a metal annulus of concave-convex cross-section, approximating a quarter of a circle as shown in Fig. 7. This member is provided with a pair of diametrically opposite guide arms 3, each provided with a guide slot 3 adapted to engage the arm 1* of the corresponding templot-support C. The curved templet C is adapte to embrace one side 0 the mandrel B andhas one edge portion w ich encircles the outer circumference of the mandrel B.

use

This edge portion is provided with a cir-' cumferential series of transverse recesses, or

sl0ts, 4, adapted to receive the inner series of steel strips which form a portion of the armor of the interliner, or tire, structur.

The recesses 4 are equi-distant from each- Y other, and thus the templet is provided. with teeth or projections 4. At points correspending with the guide-arms 3, twmof the teeth are provided with slots 4' adapted to v relation to the form.

In Fig. 7. the -cart-ass of the inter-liner is shown as-composed of a number of layers of fabric 6. These layers are impregnated with rubber cement in the usual manner and. in ,practice. the outer layer of fabric issufiiciently sticky to engage and hold the curved steel strips when they are placed in the spaces 4 and pressed against the fabric.

Fig. represents a sectional view corresponding with Fig. 7. and shows one. of the steel strips 6 in position. Fig. 4: shows a series of the. steel strips-(i in position.

It will be understood that the templet C is mounted on the mandrel in-the manner illustrated in Fig. 1 and is employed during the operation of placing the inner series of steel strips 6. The templet. C is then removed. and additional layers of fabric are applied, so that the series of strips (flare covered, these additional layers of, fabric being indicated by the nui'neral 7 in Fig. 5.- The templet G which has a slightly larger are than the templet C then 21]).Lll0tl. and.

an outer series of curved steel strips S are placed in position. r I r The templet C is provided with a series of transverse slots, or recesses, 9, adapted to permitthe steel strips 8 to be placed in position as will be understood from Figs. 5

and 6. Thus, the temple-t C has a series of spaced'tceth f); and at diametrically opposite points two of these teeth are provided with slO s adapted to receive the reduced portions of the webs of the clamps 5. which may be reversed when used in connection with the teni'plet C The spaces 9 of the templet (1" arestaggered with relation to the spaces 4: of the tcmplet C, as will be understood from Figs. 4 and 6,'thepurpose being to enable the steel-strips 8' to he so placed as to overlap the steel strips ,6 ot the inner series. The templet C is provided with a pair of diametrically opposite arms 10 which are slotted in thefsame manner as are, the arms 3 ofthe templet. (1., so as to engage the socket arms l lof the tcmplet-supports C. These guides 10 are so positioned onthe templet C as to cause the-slots S) of the templet to be staggeredwith relation to the position of the inner steel strips 6. This is important for the reason that the inner series of strips are covered by the fabric 7, and without this precaution, there would be no way of determining the proper position for the templet G Afterthe steel strips 8 of the outer series have been placed in position and pressed against the fabric 7 to which they adhere, the templet C is removed and additional layers of fabric are applied, after which the form is removed from the spider and introduced into the vulcanizer in the usual manner. I I

The apparatus described is simple and enables an interliner or tire structure of the character mentioned to be constructed rapidly and in an economical manner. It is preferred to mount the templet-supports C I directly upon the inner peripheral portion of themandrel B; and as it is necessary, in eommoirpractice, to employ many mandrels in the manufzu-ture of each size of interliner or tire, it is convenient to form the templetsupports C separately and then insert them in sockets with which the mandrel is prorality ot' supports, and an am'uilartemplet :arricd by said supports, and coacting with said n'mndreil. said tcmplet being provided circumferentially with aseries of recesses.
